I didn't know if anyone would be able to help me out with my issue but here it is. I have a rattle when the car is warm enough to idle around 600-800 RPM and it seems to be getting worse over time. The only thing done to it is the AWE Touring edition exhaust and PRL Cobra CAI. The car has around 14,500 miles on it at this time. I have no clue what it could be and I would like to see if anyone has had any similar issues with their cars before I put the stock air box on and take it to the dealer. Any help or ideas would be greatly appreciated. I have a video if anyone could explain how to post it on here.
